Abstract

1,045,383. Slide rules. MANNESMANNMEER A.G. March 8, 1965 [March 9, 1964], No. 9667/65. Heading G4B. A body member 1 rotatable relative to a frame 4 comprises, in addition to slides 9 cooperating via cursors 10, 13 with further markings on the member 1 as in a conventional slide rule, a rotatable cylindrical member 11 having a plurality of slides 12. Calculations between any one of the slides 12 which may be viewed through a slot in the member 1 and one of the slides 9 may be evaluated using the curved cursor 13. The slide rule may be illuminated by a lamp housing and reflector 8 which is rotatable relative to the frame 4.
